Mitutoyo HM-200 Series SERIES 810 – Micro-Vickers Hardness Testing Machines
• The latest electromagnetic force motor used in the loading mechanism enables the test force to be
freely selected over the wide range of 0.05 gf to 2 kgf. It is also possible to freely set the time for
loading and load dwell time. Now the benefits of absolute control over the indentation size in Vickers
hardness testing can be realized. The HM-200 series always offers the test force most appropriate for
the specimen material and shape.
• The objectives used enable a very comfortable working distance between the objective and the
specimen surface. This greatly reduces the possibility of collision between the specimen and the
objective during focussing operations. (For example, for 50X objectives: 1.1 mm for conventional
models; 2.5 mm for HM-200 series models.)
• Newly designed 'MH Plan' objectives are optimized for measuring indentation images. The lineup
includes 6 long working distance objectives: 10X, 20X, 50X and 100X for measuring indentation
images, and 2X and 5X for enabling wide-range measurement around indentations. LEDs are used in
the illumination system for their advantages of longer life, lower heat generation and higher energy
efficiency than the traditional incandescent bulb.
